Realman Robotics Open-Source Humanoid Robot (RealBOT)

Most humanoid robots are admired from a distance, behind a rope, on a trade-show stage. The Realman Robotics Open-Source Humanoid Robot (RealBOT) is built for the opposite situation: a narrow indoor corridor, a shelf at head height, a team that needs a working body to teach new tasks to. It rolls instead of walking, it carries two arms and a sensor-filled head, and its base separates from its upper body.

The product is available through this page, by quotation.

Background

RealMan and the road to an open platform

RealMan Robotics is known for robotic arms, and that lineage shows in the RealBOT. The platform is compatible with RealMan arms including the RX75, the RM75 and the RM65, and the robot itself carries dual RX75 arms. A company that has spent its time on arm hardware has built a humanoid around what it knows best: manipulation.

RealMan debuted its RealBOT Embodied Open Platform at IROS 2025, the IEEE/RSJ International Conference on Intelligent Robots and Systems. The word 'open' in the name matters. The platform accepts mainstream grippers and dexterous hands from OYMotion, BrainCo and Zhixing, and it works with both NVIDIA Jetson Orin and Digua RDK S100 compute platforms. A lab or integrator is not locked to one hand or one computing choice.

A modular body with a wheeled base

The RealBOT uses a modular architecture, with a separable wheeled base and a humanoid upper body. Wheels trade the drama of walking for steadiness and simplicity, which suits indoor work where the floor is flat and the task happens at the hands. The robot has 21 active degrees of freedom: 14 in the dual arms, 3 in the waist, 2 in the legs and 2 in the neck. The waist and neck let the robot lean toward a shelf and turn its head toward the work, so the camera view follows the task.

Both the chassis width and the shoulder width are under 465 mm. That figure is the reason the robot can pass through narrow corridors and work in dense indoor spaces, where a wider machine would have to stop at the door.

What makes RealBOT different from a fixed robot arm?

A fixed arm does one job at one location. The RealBOT moves to the job. Its wheeled base travels at 0.1–1.5 m/s and turns in place within a 690 mm radius, so it can enter a room, position itself and then work with two arms at once. Each arm lifts 5 kg, and the vertical reach of 2100 mm covers high shelves, while the horizontal reach of 1818 mm, without an end-effector, extends across a counter or bench.

Perception is the other difference. A fixed arm usually sees through one camera on its wrist. The RealBOT combines 5 depth cameras, 3 fisheye cameras, 1 LiDAR and 2 IMUs, and the head carries a microphone array. The LiDAR specification reads 90% reflectivity at 40 m, which supports mapping and navigation, while the depth cameras serve close-range manipulation. For teams working on embodied intelligence, that combination gives a robot that can both find its way and handle objects.

How do the data collection and standard versions differ?

There are two versions, and the difference lies in the depth camera. The data collection version comes standard with the Orbbec 335LG. The standard version uses the Intel RealSense D405. The RealSense D435 is available as an option. The other figures in the table describe the platform as a whole, so none is assigned to one version or the other.

In practice, choose the data collection version when your project is built around gathering demonstrations and training data, and the standard version when you want the platform with the RealSense D405 camera. Tell us your camera preference when you request a quotation.

Who is the RealBOT for?

University and corporate research labs are the clearest fit. An open platform that accepts several hands, several arms and two compute families lets a team keep its own experimental setup and avoid rebuilding it for each project. Groups collecting demonstration data for embodied AI will find the data collection version matched to that work.

System integrators and product developers are a second group. If you are prototyping a service or inspection application for dense indoor spaces, such as offices, labs or light-industrial rooms, the sub-465 mm width and the modular base give you room to test ideas without a custom chassis.

Educators running advanced robotics programs can use it as a teaching platform with a full sensor suite. If your task needs a robot that walks on legs rather than rolls, browse the Bipedal Humanoids category; for the wider range of wheeled and legged designs, see our Humanoids category.

What is the RealBOT used for?

1. Embodied AI research. The robot gives algorithms a body with arms, a waist, a neck and a full perception suite to learn from.
2. Data collection. The data collection version, with its Orbbec 335LG camera, is the one aimed at gathering demonstrations for model training.
3. Dual-arm manipulation. Two RX75 arms, each with a 5 kg payload, allow tasks that need both hands, such as carrying or sorting.
4. Dexterous-hand development. Compatibility with OYMotion, BrainCo and Zhixing hands lets teams test different end-effectors on the same body.
5. Indoor navigation and mapping. LiDAR, IMUs and wide-angle cameras support movement through tight corridors and dense rooms.
6. Voice and interaction trials. The head-mounted microphone array and the optional 6-Mic voice module support speech-driven experiments.

Frequently Asked Questions

Does the RealBOT walk or roll?

It is a wheeled humanoid robot, with a separable wheeled base and a humanoid upper body. It has 2 degrees of freedom in the legs, but it moves on wheels.

How much can each arm lift?

The single arm payload is 5 kg, and the robot carries dual RX75 arms.

Can it fit through narrow corridors?

Yes. Both the chassis width and the shoulder width are under 465 mm, which lets it pass through narrow corridors and work in dense indoor environments.

Which grippers and hands does it accept?

It is compatible with mainstream grippers and dexterous hands from OYMotion, BrainCo and Zhixing. RealMan arms including the RX75, RM75 and RM65 are also compatible.

What computing platforms does it work with?

It works with both NVIDIA Jetson Orin and Digua RDK S100 platforms.

How long does it take to charge?

Charging takes about 2 hours for the 40 Ah battery with BMS.

Where can I buy the RealBOT and what does it cost?

You can buy the Realman Robotics Open-Source Humanoid Robot (RealBOT) through this page by requesting a quotation. The cost depends on the version and options you choose, and it is given in the written quotation, not on the page.

Summary

The RealBOT is a humanoid built to go to work in places where space is tight, not to stand on a stage. Wheels give it steady movement, 21 active degrees of freedom give it reach and posture, and a wide sensor suite gives it eyes, ears and a sense of its surroundings. Open compatibility with hands, arms and compute platforms leaves your team in charge of how it is used. If that matches the project you have in mind, this page is the starting point.
